Signatures are gathered one on top of another, then secured with thread by linked stitching on the back of the fold and
through the center fold of each signature, which allows the book to open flat. Covers are flush with text pages
and are affixed with glue on a
perfect binding line.

Applications:

Business and professional books, technical reference and other manuals.

Specifications:

Signatures are gathered, one on top of another; then flexible adhesive
is applied to the backbone after the folds along the
spine are trimmed off. After the glue cools, the book is trimmed to its specific
size. Variations include notch and
lay-flat bindings.

Applications:

This is the most common type of binding for trade, scholarly, business, professional, religious, reference, and text books
as well as catalogs and manuals.

Applications:

Specifications:

Lay flat
perfect binding

A reinforcing strip is applied along the backbone of the cover. The book block is then secured with two applications of
cold glue and a bead of pressure-sensitive hot melt about 1/8" above the back edge of the front and back covers. This results in a gap
on the book's spine between the reinforced text signatures and the cover that allows the book to easily flex away from the cover when
opened. Lay-flat is a newer binding style often used as an less expensive alternative for Wire-O, spiral, and plastic comb binding.

Specifications:

A booklet binding method which inserts one folded signature into another, then fastens
the signatures with wires (staples) through the center
fold of the gathered signatures. It may be a self covered publication (same paper stock as text
) or with a separate cover. Less expensive then adhesive
binding.

This is a binding method in which the book is punched with slots along the binding edge, through
which either a continuous series
of double wire loops (Wire-O) or a vinyl plastic sheeting die cut in the shape of a comb
( GBC) or coil is inserted.

Applications:

Manuals, training materials, and specialty items such as recipe books that must lay flat.
